Can't set the domain

Are you unable to point using namservers ns01.000webhost.com
and ns02.000webhost.com?

I can’t because it would disrupt other services using the domain. I don’t understand why this does not work, everything is setup properly on my side, obviously the method 000webhost uses to detect the CNAME record is not working!

Okay can you set up an A record?

type: A
host: 153.92.9.114
design-principle.co.uk

Do you mean instead of the CNAME?

as well as CNAME sorry.

Doesn’t appear to have changed anything sadly.

Hmm I’d just point ns01.000webhost.com and ns02.000webhost.com and be done with it.

Then on 000webhost hit set url, manage domain, set MX record and paste it in designprinciple-co-uk01e.mail.eo.outlook.com.
